To all whom it may concern.-

Be it known that 1,. HARRISON A. HAnrL residing TON,-a citizen of the United States, at Myers, Nicholas county, State of Kentucky, have invented certain new and useful Improvements in Combination-Tools; and I dodeclare the following to be a full, clear, and exact description thereof, attention being called to the accompanying drawings, with the .reference characters marked thereon, which form also a part of this specification.

This invention, relates to certain new and useful improvements in combination-tools,-

and more particularly to one where a customary hand or rip saw forms the primary tool and which by a certain constructon and by "061138.111 attachments cooperating therewith,- all as shown and hereinafter described, may

also be used to erform the functions of certain other additional tools.

try square.

In the following specification and particu pointed out in the claims is found a full: description of the invention, together with; manner of use, parts, and construction,which accompanying mentioned socket is therefore arranged ac- Figure 1 shows the entire implement'comlarly latter is also illustrated in the drawings, in which plete, the adjustable attachment being held thereto merely to prevent its loss or misplacement, no use of any. kind being here contemplated. Fig.2 shows the implement in a condition permittin normal use of the saw. It may also be use as a plumb to ascertain the verticality of upright surfaces. Fig. 3 shows the implement ad usted and used as a mitering-angle. It may also be used as a level to test and ascertain horizontality'of surfaces. Fig. 4 shows the other side of the implement and the same arranged and used as a trysquare. Figs. 5 an 6 are sectional detail views, Fig.5,being part of an edge view of the implement and section on line 5 5 of Fig. 3, and Fig. 6 is a horizontal section on line 6 6 of the same figure.

In the drawings,-9 indicates the saw-blade, 10 the handle, and 11 its shank whereby the same is attached'to the broad end of the blade shank is provided with two edges 12 and 13,

which are arranged parallel to eachother and angles to edge 14 of the saw-b ade.

These functions contemplate use as a mitering-angle or miter-g ing-square to lay off angles of forty-five de-. grees and comprise also all the possible uses, of a'customary square, like a carpenters or at right angles to the back edge 14 of the saw-blade.

A leveling instrument 15 of customary con struction is mounted on or embedded into edge 12 of shank 11 in a manner so as to be parallel to this edge, thus bein also a}; ri ht n t 's condition the implement may be used as a plumb to ascertain the verticality of an upright object or surfaceas, for instance, as shown in Fig. 2 at 16.

By providing an arm 17 and mounting the same soasto be parallel to edge12 and to level 15the implement may be used as a leveling instrument to ascertain horizontality of arranged accordingly and with all these uses in view. This shape and size is that of a flat elongated rectangular blade with parallel longitudinal edges 20 and 21, and the abovecordin ly to form a guideway which may receive this blade and at the same time hold it firmlyto its right-angular position with reference to edge 14 and to its parallelism with reference to edge 13 of shank 11 to serve in the first instance as a complementary part of the try-square shown in Fig. 4 and in the other instance as a constituent part of the leveling instrument shown in Fig. 3. This socket and guideway is constructed by using edge 13 of shank 11 as one of its sides and the alined surfaces 22 of two posts 23 as the other side, between which the edges of arm 1 7 closely fitwhensaid arm is flatwise inserted. (See Figs. ,2 and 3.) This guideway and socket is completed by using" parts of the saw-blade, andit is closed outwardly by a cap 24, secured in place by attachment to posts 23 and to shank 11, the attachment being in any suitable way,- as by screws, rivets, or other equivalent means. Screws 25 are shown as used, a lug 26 being provided at the point of attachment to shank 11. Set-screw 19is also seated in this cap,-but could equally as well be I then from the opposite side.

1 blade andone,

mounted in the saw-blade, the insertion being It will now be seen that arm 17 is detachably held to the saw-blade and also adjustable in the direction of its len th, the movement being a sliding one and c osely fitted in a manner that at al times the arm preserves its proper angular relation with reference to edge 14 of the saw-blade, which means also parallelism with edge 12 of shank 11,u on all ofwhich the use of the implement as a eveler and as a try-square depends. By cutting a trian ular notch in from back edge 14 of the saw-b ade with one of its lines disposed at ri ht angles to this back edge and in line with e ge 13 and b cutting shank 11 away, as shown at 27, to orm the other line and by finally shaping this notch so that this line or edge 27 forms also an angle of one hundred and thirty-five degrees with edge 13 of shank 11 or one of forty-five degrees with the other line of the notch or with arm 17 when this latter is inserted the implement may also be used as a mitering-square to measure andlay oii angles of forty-five degrees, as best shown in Figs. 1, 2, 3, and 4. This edge 27 is preferably covered or lined by' a metal plate or strip to protect the wood.

Of the square formed as shown in Fig. 4

either the inner or the outer angle may be used. The inner an le is formed by edge 14 of the saw-blade an by edge 20 of arm 17. The outer angle is formed by edge 21 of arm 17 and by an internal edge 28 on the sawblade, which edge'is obtained by slotting the saw-blade in the manner shown. All four edges are provided with suitable graduations and scales, showing, preferably, inches-with customary subdivisions, the same as are used in regular carpenters squares.

It is sometimes desirable for certain'measurements and calculations that the. graduations-on both edges of the angle start from the vertex or point of the same. Therefore and in order tofacilitate location of this point for such purpose or for any other I rovide complementary notches, one, 29, in t e saw- 30, in arm 17, which for this intended purpose must re ister, arm 17 being adjusted accordingly by s iding in its guidesocket.

After use in any capacity and when neither the saw nor arm 17 are required this latter may be held to the saw merely to keep the parts compactly together by insertion between posts 23, as shown in Fig. 1, and in which position it is held by set-screw 19. This insertion should be such that no part of arm 17 pro'ects beyond the area of the saw-blade, an it may be in either one of the positions as shown in Fig. 1, one position ap- A pearing in dotted lines.

Having described my invention, I-claim as new 7 1.
